WILLIAM T. LAMM, OF BUFFALO, NEW YORK.

ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 696,056, dated March25, 1902.

I Application filed July 6, 1901- Serial No. 67,328. (IlomodeL) T aZZwhom it may concern.- I

Be it known that LWILLIAM T. LAMM, a ci tizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Ash-Sifter, of which the following is aspecification.

This invention is an improved ash-Sifter, the object being to provide asimple and practicable construction of ash-sitter by means of which thedust and dirt can be quickly and. easily separated from the cinders andthe said cinders withdrawn from the sifter for the purpose of beingreburned.

With this object in view the invention consists in the peculiarconstructionof the various parts and in their novel combination orarrangement, all of which will be fully described hereinafter andpointed out in the claim.

In the drawings forming part of this speci fication, Figure 1 is avertical sectional view of an ash-sifter constructed in accordance withmy invention. Fig. 2 is a side elevation of the upper section, the topbeing removed. Fig. 3 is a detail perspective view of the sieve. Fig. 4is a detail view illustrating the relative position of the two screens.

In the practical embodiment of my invention I employ a lower section orreceptacle A, which is preferably made of sheet metal strengthened bymeans of beading-grooves; but it will be distinctly understood that thislower section or receptacle may be made of any desired material andinfact may be an ordinary barrel. Fitted into the'upper end of thislower section or receptacle is a cylindrical case B, the lower end ofwhich is adapted to fit into the upper end of the lower section, and abead B limits the inward movement of the said case. 0 indicates the topor cover, which is fitted into the upper end of the case B. A Wirescreen D is arranged within the case B adjacent to its lower end, saidscreen being inclined, as indicated, its lower side being arrangedadjacent to an opening E, produced in the side of the case, said openingbeing normally closed by means of a door F, which slides in theguideways F, secured upon the exterior of the case B. A circular sieve Gis arranged within the case B adjacent to its upper end, said sievehaving a rod H extending rearwardly from its frame, said rod being roundin cross-section through its entire length. A rod I projects forwardlyfrom the opposite side of the frame of the sieve, that portion of therod adjacent to-the frame being round in cross-section, while theportion 1 adjacent to the handle K is square in cross-section. The rod Iextends through a horizontal slot 1*, produced in the side of the case,and the square portion I normally rests in the said slot, a coil-springL being arranged around the rod I between the frame of the sieve andtheinner side of the case, thereby serving to hold the square portion ofthe rod in the slot 1 and securelymaintain the sieve in a horizontalposition.

In operation the ashes'to be sifted are placed in the sieve G, the cover0 of course being removed for the purpose of introducing the ashes, andthe said cover is then'replaced. The door F is also closed. The sieve Gis then vibrated or moved rapidly back and forth by means of the handleK, and the ashes or fine dust and dirt will pass through the sieve andalso through the screen D down into the bottom receptacle A. Thevibrating operation of the sieve is continued until all the ashes orfine dust has been separated from the cinders, and the cinders remainingin the sieve are dumped upon the screen D by turning the said sieve uponthe rods H and I, it being understood that the handle is drawn out todisengage the square portion I from the slot I and bring the roundportion of the shaft into the said slot, thereby permitting the sieve tobe rotated upon therods H and I as an axis. The cinders so dischargedupon the screen D will gravitate to th lower side of the same, and byopening the door F the said cinders can be quickly and easily removedfrom the sifter.

It will thus be seen thatI provide an exceedingly simple device by meansof which the ashes and cinders are quickly separated, and

mit the front rod to be pulled out to remove 10 the square portion fromthe slot for the purpose of rotating the sieve, substantially as setforth.
